Dab tsi yog 440C stainless hlau
Qib 440C stainless hlau yog cov pa roj carbon siab uas, tom qab kev kho cua sov, tuaj yeem ua tiav qhov siab tshaj plaws, hnav tsis kam thiab lub zog ntawm txhua qib stainless hlau. Cov yam ntxwv no ua rau qib tsim nyog rau kev siv xws li lub rooj sib txoos valve thiab pob bearings. Ntawm qhov tod tes, qib 440A thiab 440B stainless hlau muaj cov khoom zoo sib xws - tshwj tsis yog tias feem pua ntawm cov pa roj carbon monoxide hauv qib 440A qis dua me ntsis.
Tag nrho peb hom ntawm 440 steel feem ntau yog siv. Txawm li cas los xij, qib 440C yooj yim dua kom tau txais ntau dua li lwm qib. Qib 440F yog ib qho yooj yim rau txheej txheem ntawm Qib 440 series thiab tseem muaj cov ntsiab lus zoo sib xws li qib 440C. Martensitic steel yog cov hlau hardness siab uas feem ntau yog tsim los ntawm cov txheej txheem uas yuav tsum tau quenching thiab tempering kho.
Cov qib no muaj kev tiv thaiv corrosion tsawg dua li lwm cov qib austenitic. Daim ntawv thov ntawm martensitic steel yog txwv los ntawm kev poob ntawm lub zog vim yog tempering ntau dhau ntawm qhov kub thiab txias thiab poob ntawm ductility ntawm kub hauv qab xoom.
